Mass of box = 300 Kg
Gravitational potential energy = 29400 J
We know,
Gravitational potential energy = mgh
h = GPE\over mass × gravity
= 29400\over 300 × 9.8
= 29400\over 2940
= 10 m

(a) Calculate the change in the gravitational potential energy of the skier between A and B. (b) If 75% of the energy in part (a) becomes the kinetic energy at B, calculate the speed at which the skier arrives at B.(Take g = 10 ms-2).
